Do we know if the person who let the shooter back in the exit door before the shooting is still alive? If it were me, I’m not sure I could live with it. As for anyone else preventing it all, we’ll have to wait until they investigate how he purchased guns and bullets, and what the permissable capabilities of those weapons were in the eyes of the law. To be sure there will be a lot of 20/20 hindsight analysis to come. In the end laws are volunteerily followed (or not) and justice is imperfect at best when it comes to cleaning up the mess. I am very dissapointed at Obama’s failures to bring justice to the 1000s of innocent americans shot by others on his watch.

Early reports (very early) are he bought a ticket and let himself out the door and blocked it to get back in.
